Petasites japonicus Miq. (fuki) and Phyllostachy sρubescens Mazel (mosochiku，
bamboo shoot) were studied concerning its possibility as a frozen product. lt was
found that after thawing the vegetables were extremely sabby and soggy，resulting in
an undesirable food for cookery. Histological findings revealed that the delicate thin walls were ruptured in comparison to the fresh or blanched samples，resulting in excess amount of water leakage.
